The Diploma for Non-Domestic Energy Assessors has been developed by City & Guilds in line with the National Occupational Standards, which supports Government initiatives in providing a competent workforce to meet the requirements of the Energy Performance of Buildings Directive. This directive sets out the need for Energy Performance Certificates (EPCs) similar to consumer friendly fridge ratings to be produced for buildings.

The qualification is essential and is relevant to anyone who currently works within the property market or wants to become a Non-Domestic/Commercial energy assessor.
